Abstract: Drive assemblies for surgical clamping and cutting instruments, as well as surgical clamping and cutting instruments using these drive assemblies, are disclosed. The drive assemblies may include a drive member, a locking member mounted to the drive member, and a spring. The drive member may be configured to releasably engage at least one of a knife or a shuttle of a surgical clamping and cutting instrument for translating the knife and/or shuttle in a distal direction through a firing stroke. The locking member may be movable from a first position permitting distal translation of the drive member through the firing stroke, and a second position inhibiting distal translation of the drive member through the firing stroke. The spring may be configured to bias the locking member toward the second position.

Abstract: A surgical stapling instrument is configured to dissect tissue, apply a linear staple line along one side of the tissue dissection and apply a suture, such as a purse string suture, to the other side of the tissue dissection. The instrument comprises an elongate shaft, first and second jaws configured to open and close and a cutting element. The instrument includes a first row of staples in each of the first and second jaws having a suture extending therethrough and a second row of staples in the second jaw. A drive member is configured to translate distally through the end effector to dissect tissue with the cutting element, drive the second row of staples into the tissue on one side of the dissection and to apply the first row of staples and suture in combination to form a purse string suture on the other side of the tissue dissection.
